Type: Holiday Event
Date: December 31st - January 1st
Location: Stormwind, Thunderbluff, Booty Bay
Fireworks
The innovative and artistic engineers of Undermine have been slaving away since their display of pyrotechnics in July. Their latest and greatest -- not to mention highly dangerous to operate -- creations will be on display in the cities of the world every hour after sunset. Keep your eyes to the skies, and be sure to stick around for the finale!
Potent Potables
What good is a party without sampling some of the brewers' delicious work? Kegs of the finest brews are available in the cities of Azeroth, bringing good cheer as we bid farewell to the old year. Cups are available for all party-goers; simply pick one up and fill up at the keg to warm your belly and lift your heart!
Revelers, All
Many soldiers formerly abroad have come home to engage in the festivities. Share in the merriment and dance with the revelers, or, if you're so inclined, blow a kiss to one that catches your eye. It's all in fun, after all; they appreciate the attention!
Bolded the important parts.
